INFLUENCE OF MEDIUM COMPOSITION ON GROWTH AND BIOSYNTHESIS OF EXOGLYCAN BY CRYPTOCOCCUS-LUTEOLUS (SAITO) SKINNER STRAIN-228

The influence of medium contents on the growth and extracellular polys accharid production by Cryptococcus luteolus had been investigated. It has been found, that the nitrogen sources little affected on the proc ess, excepting substanses didn't supported growth completely. The type of carbon sources had a mote effective influence on the process, but all the carbon sources supported the polysaccharide production. The co ncentration of microelements and yeasts extract charged growth more th an polysaccharid biosynthesis. The influense of factors and its couple interaction had been quantitetively estimated by chance balans method . The factors had been picked out for a following process optimization .
